NIgeria:
NNS Ambe Type 502 class LST
The Type 502 class LSTs Ambe and Ofion were designed by HDW as a private-venture for sale to the West German navy, which was not interested.
Both ships suffered minor fires during the 1980s which were repaired, but maintenance on the bow ramp machinery was poor and by 1992 both vessels had non-operational ramps. Several sources state that both ships had ramps welded shut, rendering them transports instead of LSTs.
NNS Ambe, one of the two amphibious vessels acquired by the Federal Government of Nigeria in 1978 was said to have been the country's only operational Amphibious war ship used for lifting a battalion and their equipment as the second, NNS Ofion, was almost a carcass as major parts have been used to keep the burnt Ambe in shape. The ship had a capacity of lifting a battalion of 600 soldiers and their equipment at once. NNS Ambe, which became fully operational in the 1980s, played a significant roles during the ECOMOG operations in Liberia and Sierra Leone.
In 2010, troop carrier landing craft NNS AMBE of the Nigerian Navy under repair at Navy dock yard, Wilmot Point, Lagos had caught fire under her starboard bridge deck. Ambe suffered a severe fire which started in her cargo deck and spread upwards under the starboard side of the bridge. The bridge and radio room were destroyed, and the crew berthing spaces severely damaged. The fire burnt out the entire bridge and part of the accommodation, leaving the main mast tilted to starboard on top of the compass deck which had also been seriously damaged.
In August 2010 a civilian company, Atlantic Marine Services, was contracted to remove the mast. AMS was called in to remove the mast as it was threatening to collapse. With the help of their tug EXPLORER they mobilized their 1000dwt barge H457 and their Leibherr HS871 crane alongside the NNS AMBE. The mast was secured, cut and lifted off on 13 August 2010 and delivered to NNS Olokun maintenance yard for further dismantling and repair. Since them Ambe was moored at the Wilmot Point naval dockyard in Lagos awaiting repairs.
