    Brief

    The Northern Lighthouse Board (NLB) seeks an experienced contractor to perform a 40,000-hour major service overhaul on the starboard forward 720kW Wärtsilä 4L20 diesel engine aboard the NLV Pharos, a DP(AA) Buoy Tender. The work is scheduled for January 2027 (4th–20th January) and will be conducted onboard the vessel on Scotland's east coast. The scope includes preparatory component work (cylinder heads, valves, governor components), power assembly and mechanical overhaul (bottom-end, crankshaft, pistons, liners, main bearings), pump and ancillary overhaul (pumps, thermostats, coolers, exhaust), and reassembly with measurements and commissioning trials. NLB will supply all spare parts and consumables. Fuel pump overhaul and injector maintenance will be handled by third parties and ship's staff prior to the contractor's arrival. The contractor must have access to detailed tender documents via the Delta e-sourcing portal. Accommodation and subsistence will be provided by NLB for the duration of the service. Quotations close 27th November 2026.
