Versatile crane for new survey catamaran
MKG’s powerful 20 m/t radio controlled hydraulic knuckle boom crane will play its part in coastal survey.
German deck equipment specialist MKG has just fitted out a new purpose-built coastal survey catamaran with a powerful 20 m/t radio controlled hydraulic knuckle boom crane.
The ultra-quiet and extremely economical Bibby Tethra is operated for survey contractor Osiris Projects by one of the oldest shipping companies in the UK, Bibby Maritime Ltd.
It is a 27.5m semi-SWATH coastal survey vessel, ideal for operating in various sites around the UK where it will undertake the company's survey activities within the oil & gas and the offshore renewable energy sectors, collecting high quality survey data.
Asked why MKG was given the contract, the company’s managing director Dr. Susanne Peters told MJ, “I think that it was due to our competitive price, the good quality of the crane that we offered (made in Germany), and also its versatility for handling equipment on board as well as in connection with the collection of data from the sea bed.”
As all MKG marine cranes, MKG's model HMC201a5 is manufactured according to DIN 15018 to meet all marine specifications for provision/service cranes of type A, with minimum 5° heel and 2° trim at full load. It will be responsible for handling all equipment connected to the vessel's survey activities, such as cable and pipeline inspection, tracking, or grab sampling.
The HMC201a5 is a stationary mounted hydraulic crane with a lifting capacity of almost 6,000 kg at 2.8m and up to 910 kg at its maximum horizontal reach of 14.43m. It has a minimum working radius of only 0.5m and comprises a Load Sensing System (LS). It is fully radio remote controllable and is also equipped with a black box, an electronic control system featuring a load moment limiter, actual load information, damping control for the lifting cylinder, and a diagnostic system indicating all malfunctions on a digital display. The crane's hydraulic winch manages 4,000 kg pull at single line, and 6,000 kg pull at reduced speed for maximum load.
