Steel Cutting Ceremony of the Robert Allan Ltd. Designed Offshore Tug

[By: Robert Allan Ltd.]

October 9, 2023 marked the start of steel cutting for the Robert Allan Ltd. designed offshore support vessel RAmpage 4100BB-H for Buksér og Berging, Norway. The OSV will be constructed at the facilities of Uzmar Shipyards, Turkey.

The RAmpage 4100BB-H is designed to satisfy the general demands of the offshore industry and to be built for inshore and offshore worldwide operation. The vessel will be intended to carry out towing, anchor handling, and limited deck cargo transfer. During the design, serious attention was given to minimize hull resistance and fuel consumption at cruising speed. The hybrid type propulsion system includes effective power management which allows significant operation of the vessel on electrical propulsion motors without engaging main engines. All engines will comply with IMO Tier III and will be based on the best available technology for the low emissions and fuel consumption. The offshore vessel has a unique towing system arrangement with one double drum side-to-side AHT winch capable to work astern and ahead using a compact tunnel designed for the towing line. Operations astern can be carried out with two towing lines simultaneously by utilizing two independent winch drums, two shark jaw & pin units and double drum stern roller.

The main particulars of the RAmpage 4100BB-H are:

• Length, moulded: 41.2 m
• Beam, moulded: 14.5 m
• Depth, least moulded: 6.6 m
• Maximum draft (navigational): 6.6 m
• Gross Tonnage: 1099

Performance is estimated to be:

• Bollard pull: 125 t
• Free running maximum speed, ahead: 15 knots
