QUESTIONS AND ANSWERS.
ONE, How many lifts can be reduced during a standard well operation by using new technologies?
 HSE safety issue
Answer in brief: 5400 minimum skip lifts required to lift 300 skips from site to rig and back to recycling plant.
300 CBs can be packed in two containers cutting down on possible HSE Incidents by at least 400%.
What is a standard well? (Unknown), what is the depth and formation pattern what is the rock formation and density and what is the average sample density. Mud weights wet or dry cuttings?           Comprehensive Well evaluation required before calculations possible
I can however give you an “example only” of a theoretical container calculation.
Hole section,  17.5           16           12.25           8.5  
Feet                  5000.       65000.     14096.        191400
Tonnage         736.33     800.16      1017.21     104.16
Containers     184           200           254              26       
  • Total skips required            664
  • Max skips possibly used in one day   77
  • Additional Volumes  X 1.5
  • Containers
  • Per day       DIV/0      76.21        69.36        4.96
 
Lets say at least 1200 Tons of cuttings are going to be generated in the first 7 drilling days , total amount of skips required for cuttings containment =300.
Skip empty shipping weight 2 ton each x 300 = 600 Tons one way both ways 1200Tons.
300 CBs packed into 2 x 20 foot containers x 50 kg each = 15000kg, + Container weight. ?
No allowance for drilling speed, ballast control operations required to ensure rig stability, Well formation, casing, rough weather or mechanical breakdown has been taken into consideration of the above as it is for “example” only.
 
 
  •  “300” x 2 ton empty skips need to be fork lifted on to 24-5 ton articulated trucks.
  • Loading only 12-14 per truck at a time is possible due to skip size and weight, so this would require “24-5” trucks to be hired or one 32 ton truck used 24-5 times.
  • Transport truck costs £105+ each trip from Bridge of Don to Aberdeen harbour which = £2520 minimum trucking fees one way only.
  • Fork lift and driver one and a half ours each load at £50-55 per hour,
  • Load at site £1200
  • Unload at harbour £1200 minimum.
  • When the supply boat arrives at shipping point another “300” crane lifts are required to load on to boat
  • 300 at destination off supply boat on to rig.
  • That amounts to (1200) one thousand two hundred lifts so far which equals one lift per storage “ton”.???
  • Or over 12 x 24 hr days.
  • Crane operator wages £350 per day minimum over 7 days + at least 150 hrs loading on to supply boat at harbour
  • 150 hrs unloading at rig site.
  • Using 300 skips each lift would take roughly one half hour each,
  •  Lifted from supply boat to rig. Personnel required  .One crane operator one rig crew and one supply boat crew minimum.
  • This works out to be at least 150 non stop crane operator hours, which is virtually 7 days x 24 hr taken up by lifting skips.
  • For reference if this were at all “possible “crew costs would work out to be no less than £1850 for one crew each working a 12 hour shift x 7 days £12950 x 2 shifts,
  • Totalling £25900 plus supply boat costs over that 7 days just for unloading skips on to Rig.
  • This calculation is highly theoretical and is used to show time and man power consumed by skip Ship to Rig lifting. 
  • No rig has the deck strength or the free space necessary to contain 300 skips or 600Ton empty weight all at one time. 1800Ton Full weight.(Remember No stacking laws)
  • It has also been calculated by at least three Major Oil Corporations that each skip gets lifted at least another 10 times once loaded on board the rig.
  • I.E. 300 skips x 10 = 3000 + 1200 lifts to get to destination = 4200 lifts before leaving rig for the return  journey. Given that each skip takes about half an hour to move this will amass to nearly (90 days) three months x 24 hour days taken up by the crane man and all the necessary deck crews.
  • 300 CBs will fit into 2 (two) 20 foot containers
  •  Which is only 2 lifts each time?
  •  (Only one container would be required if CBs were to be delivered vacuum packed direct from factory).
  • When 300 skips arrive on most rigs there is no surplus storage room available so it is essential the supply boat has to stand by and act as off rig storage.
  • At over 14k per day (North Sea) this can be very expensive.7 days loading at harbour 7 days unloading at rig + 3 day sailing to reach destination X £14k per day= £238k + 7 days necessary  for the supply boat to act as standby for offshore storage use
  • £98k, Total of £336k before return journey.
I know of one particular incident where two supply boats had to act as off rig storage for over 30 days( £840k)Shipping costs based on £336k for one supply boat only,
NB.300 skips will not fit into one supply boat.  (No stacking laws.)Crane operators wages at £350- per day  x 7 days + 7 day loading at harbour and 7 days offloading next to rig =£7350.00p
Harbour deck and rig crane crews for loading unloading 3 men + one radio controller + two ground/deck crew,, (HSE laws,)each man again at £250 a day x 6, 3 on boat 3 at harbour = £1500  for day one loading
  • Forklift  loading                                                       £2400.00p one way minimum
  • Trucking                                                                   £2520.00p one way minimum
  • Ship / stevedores x 6 loading at harbour.          £1500.00p one way, x 6 for true cost £9k.
  • Deck/rig crew x 6 one day unloading to rig.      £1500.00p one way, x 6 for true cost £9k.
  • Rig deck crew x 3 over 7 days drilling                £5250.00p
  • Crane operator loading at harbour.                    £2464.00p one way
  • Crane operator unloading at rig                          £2464.00P one way
  • Crane operator X 7 Rig days drilling                  £2464.00p
  • Shipping loading at harbour                                £98000.00p crane operator takes 150 hrs to load
  • Ship unloading at rig                                             £98000.00p crane operator takes 150 hrs to unload
  • Ship 3 days sailing                                                £42000.00p one way
  • Supply ship used as off rig storage x 7 days    £98000.00p
 NB this should be multiplied by at least 2 as it is impossible to load 300 skips on to one supply boat. No stacking laws
  •  Cost so far is over £356,562,00p just to get 300 skips to rig, these calculations are based on hands on direct involvement with skips no other associated involvement accounted for, this is one way only.
  • No rig down time at an additional £300k+ per day or additional staff involvement is considered in this equation.
  • Add the return journey back to recycling plant and these 300 skips will have cost theclient well over £713,124.MINIMUM.
  • (Please Note) No account of expenditure for costly skip filling equipment, indispensable for loading skips has been included as there are so many different filling options.
  •  CBs can design and build an automated carousel system or custom design a fill station to fit in with existing skip filling equipment to assure clients should this option be required.
 
TWO,  Rig Operation Down time, due to not having CBs and potential savings by having it.
  • Many North Sea Rigs have Roto Mills expensive vacuum systems and slurrification units on board these days but very few North Sea Rigs with these have a contingency plan for emergency storage.
  • Any stop in the drilling program due to mechanical break down or unavailability of conventional steel containment will be expensive.
  • Rig down time costs run at well over £300k per day in the North Sea.
  • Utilising (CBs) a very innovative lightweight collapsible containment system, weighing only 50kg each (specifically designed for waste cuttings containment and transportation) as emergency storage greatly reduces the risk of any down time caused by mechanical failure or most importantly, due to lack of containment
  • Caused by weather,
  • Mechanical failure 
  • But most important by not having the foresight to understand the cost efficiency of CBs purely for use as emergency containment
  • ( Do You have a Contingency plan )
The CB system take up very little space, can be stored in places inaccessible to conventional skips, each can be man handled when cranes are down this must be regarded as very favourable.               
          4 days down time, £1.200.000.00p (One million Two hundred thousand) 
          NB. (Every one has life insurance but no one ever wants to use it)


THREE, What do I deliver just a bag or a service?
  • With wellover 7 years of research and development behind the final production of manufactured goods, CBs are not just a bag?
  • Destruct testing was all witnessed by the DNV necessary to prove that CBs were capable of being lifted from Rig to Ship;
  • Calculations show that CBs are competent of lifting well over the DNV ,agreed SWL of 7 to 1;
  • CBs can withstand a free fall drop from 75 feet fully loaded without incident.
  • CBs supply an instruction manual with every CB container shipment of goods.
  •  CBs also offer a training course on product handling usually to the recycling contractor’s crews as they will be the most likely people to be filling the CBs on/off the rig.
  • CBs also offer custom designed fill frames to fit in with existing Rig equipment.
  • CBs also offer one off designed up turning frames for land use, these fit in with existing forklifts at recycling site.
 FOUR, Success story’s who bought (Rented)the product service and how do they rate it.
Outright sale of CBs is only for overseas customers only. North Sea all clients prefer to rent.
Offshore sea trials conducted by Shell.
  • Oil Tools have used and recommended the CB system at one point supplying several North Sea Rigs. KMC is now called Scomi.
  • We are at present conducting talks with other waste processing companies .
  • Previous CBs supply to,
  • CNR,
  • Combined Corporation Ltd,
  • Apache,
  • Talisman  
  • Paladin 
  • Petrrofac, have all used the CB system and finally
  • PSL now Haliburton, are using our new TPU acid resistant Sub Sea bags, these we designed and manufactured in just under two months early 2007 .These are now in constant repeat use by the company as opposed to the costly inferior throw away system PSL formerly found necessary to use.
We have designed Oil Spill containment bags for Briggs marine Aberdeen, Designing Sub Sea chemical containment bags for (Shell-EXPRO-BP) (JV) Oceanteam has a requirement and another on going project for Fugro .We are also developing the latest pipe repair mould system in conjunction with Aubin Ltd.
 
 
 FIVE, How do you manage dirty bags and what is the realistic lifetime for a bag
Materials and construction are designed to last 10 years with a CB factory guarantee of 3 years on any materials or manufacturing defect.
  • Cleaning the CBs is up to the recycling agent as no contaminated content can be allowed to leave the recycling plant .
  • Each CB must be cleaned before leaving recycling plant as failure to adhere to this will incur large fines. (HSE Laws and Duty of care)
  • Exactly the same cleaning procedure applies to CBs as when one uses skips.
  • Only licensed waste holders are allowed to handle and recycle waste products.
  • Any illegal waste contact residue left in the inner liner of any CB when returned at end of contract would be sent back for re/cleaned at recycling centre. The loss of potential hire due to delays in cleaning + transportation costs would all be charged for as extras. 
 SIX, How do you manage the requirement to lifting?
  • CBs are manufactured as one complete item and (NOT) classified as individual parts.
  • CBs have “6” x 50 mm plastic covered green polyester webbing legs each certified to 4000kg with a MBL of 9000kgs.
  • These are attached top and bottom to Two 10,000kg round slings  with a MBL of 20,000kg, finaly terminating at top on to a steel quad lifting ring.
  •  
  • CBs production procedure surpasses most 5000kg water load test bags having a SWL of 7 to 1.
  • CBs have many uses a load test bag has only ONE?
  •  
  • CBs have under gone stringent testing necessary for rig to ship lifting all witnessed by the DNV .
  • Having the choice of  manufactures,  all have achieved the latest ISO certifications.
  • Each factory adheres to the following manufacturing regulations DNV.CN 2.7.1 for Flat woven slings, BS EN 1492-1-2000 Round Slings to BSEN 1492-2:2000 or BSEN12195-2-2000 conforming to the European Machinery Directive 98/37EC .
  • Each CB has a minimum safety factor of 7-1.
  • We have recently achieved Germanischer Lloyd certification for one of our  factory’s  and we are in the process of gaining ABS certification .
  • All CBs manufactured over the last 2 years have undergone compulsory re/certification by Global Lifting at the Bridge of Don Aberdeen and have continually passed this stringent inspection adhering to the following regulations, 
  • Lifting operations and Lifting Equipment Regulations 1998 S.I.No 2307
  • The Supply of Machinery (Safety) Regulations 1992 S I No 3073
  • The Provision of Use and Work Equipment Regulations 1998 S I No 2306
  • All when re examined were found to be free from flaws or defects.
SEVEN, What do you have available
  • We have over 000 on hire at present with 00 ready to go packed in 0 CB 8x6 Containers .
  • Additional stock  is restricted to a minimum of about 00 at any one time.
  • However, manufacturing times are very fast as we always keep a stock of materials at our factories.
  • Our overseas manufactures are the fastest given one weeks warning prior to production and an additional one month to complete manufacturing.
  • 250-300 new CBs can be made available
  • 500 could be manufactured in the same time if we used both of our overseas manufactures.
  • We can also offer the option of staggered delivery system.  
  • Shipping by sea 6 weeks or 4 days by DHL to UK, the choice is available. 
EIGHT, Previous Sales (Rental) .
  • KMC Oil Tools,. KMC is now called Scomi.
  • CNR ,
  • Apache ,
  • Talisman
  • Paladin,
  • Petrrofac, have all used the CB system and finally PSL (now Halliburton) are using our new TPU acid resistant Sub Sea bags, these we designed and manufactured in under two months IN 2007.
 NINE, Income, Investment and Profit.
  • Accounts held by Grampian Accounting .However I am at liberty to reveal
  • CBs company inventory is paid for in full. 
  • CBs having no outstanding debt or creditors .
  • CBs are also showing a vigorous profit  over the last 2 years.
  • CBs have a substantial line of credit with The Commercial department in Royal Bank of Scotland,  should they ever be in need of this facility for dealing with unanticipated over seas developments.
  • CBs at present have Architects working on drawings for new warehouse premises close to Aberdeen Harbour.
TEN, Prospect for the coming year. 
  • Expro, Shell and BP are working in conjunction on the AX-A Project require several custom built CBs.
  • This will be a global first for the Oil Industry with CBs Sub Sea bags undergoing rigorous testing to withstand the pressures found at a depth of 10000 feet.
  • No conventional steel containment is competent of enduring the kind of pressures found at such a depth.
  • To achieve this project using conventional methods, umbilical’s lines would have to be specially constructed.
  • Each line taking over one year to manufacture, costs would equate to over 1.5 million for each line x two as a back up line is necessary due to pre- program expenditure of hiring a Semi Submersible to pre-position above the work site.  
This can now be achieved using one survey ship with custom built CBs on board, saving the client millions.
  • Other interested clients include ,
  • Shell
  • Briggs Environmental
  • BP
  • Expro
  • Fugro
  • TRS ,
  • Halliburton
  • Maersk North Sea,
  • Maersk Venezuela.
  • China National Oil Company Asia,
  • BP Azerbaijan.
  • Cargo Link Canada,
  • Nexco Engineering Services Africa,
  • Statoil Hydro 
  • Fnally we have been in discussion with an on going client regarding possible CB agency agreement at their 12 company  global locations.
ELEVEN, Contract price, Sales verses Rental.
As you are aware very few Oil companies will undertake to purchase equipment out right as they regard some types of stock as an unnecessary burden which in turn requires constant monitoring.
Costs, omited due to fluctuating commodities market,increasing shipping ,material and manufacturing costs
CBs can be rented in the North Sea for a guaranteed 000  days at between £00-00 GBP per day depending on quantity and quality of liner asked for by client. (00) Minimum
  • CBs can be rented for a guaranteed 30 days at   £00-00 GBP per day
  • CBs 8x6 mini containers rent at                               £00 GBP per day.
  • Various fill hoops and hoppers                                £00- GBP upwards per day.
  • Various land site up-turning frames                        £00 GBP per day.
  • CBs Sub Sea 1000kg bags are for sale only,
  • CBs can be used in combination with any amount of additional units. 
  • Every Sub Sea CB has double fittings for use in combination. Use 10 x 1000lt Sub Sea bags in tandem =10,000lt chemicals contained.
  • Handling demonstration and introduction to hands on or video instruction courses for the use of CBs can be arranged at a cost of £000 per man per day + travel and on site expenses.
TWELVE, There is no stand by rate for emergency containment; day rate will not differ from when in use.  It has been found to be practically impossible to track CB usage once client has received delivery of product.
