		Once onboard the vessel, the structures will be secured and made safe to survive extreme weather conditions. The vessel will sail to shore and deliver the structures to a refurbishment or dismantling site. The platform removal process is displayed in the figures at the end of this brochure. Distinct advantages of Pieter Schelte over traditional lifting methods and alternative concepts are: minimum offshore preparatory work on topsides: single piece lifting; no cleaning and separation of process facilities; no re-instatement of lift points and rigging on every module; minimum subsea cutting operations: single piece jacket removal; maximum safety to personnel: very limited activities offshore; maximum protection of the environment: handling of hazardous materials only within the onshore dismantling site; Visit our website for more information.
Excalibur Engineering bv provides a safe and cost effective approach to the removal of large oil and gas offshore platforms. It will commission a dedicated vessel, Pieter Schelte, with the capability to remove platform topsides of up to 48,000 tonnes (53,000 sh.t.) and jackets up to 25,000 tonnes (28,000 sh.t.) in a single lift operation. In addition to platform removal, Pieter Schelte can also be used for platform installation. Detail engineering has started, and tankers suitable for conversion will be acquired in due course. Delivery of the vessel to the market is set for 2006. The conversion of two 300,000 DWT tanker hulls provides the basis for Pieter Schelte, a catamaran type vessel with the following principal dimensions:	Length: 345 m / 1130 ft Width: 118 m / 387 ft Depth: 28 m / 93 ft Slot width: 52 m / 171 ft Enlarged slot width: 77 m / 253 ft Slot length: 114 m / 375 ft The overall size of the vessel provides considerable stability, allowing removal operations to be undertaken in relatively severe sea conditions. A hydraulic motion compensation system further improves vessel workability by eliminating load impacts during topsides removal operations. Topsides are lifted in one piece at their natural strong points. The topsides lift system will attach to the legs of the module support frame of the topsides. Jackets can also be removed in their entirety by lifting and tilting them onto the deck of Pieter Schelte.
