摘要
A semi-submersible pipelaying watercraft is disclosed, which is particularly suitable for operating under particularly hostile marine environments, said watercraft comprising a composite ramp of special construction for launching the pipe to be laid, a system for determining the craft's position and a control system, governed by electronic computers for automatically positioning the craft. An internal inclinable ramp is coactively combined with an external ramp and the internal ramp is equipped with a locking system and with a displacing system, hydraulic controls being provided for moving both the internal and external ramps. The electronic computers are two and one of them makes the calculations for determining the design parameters, whereas the other computer receives the actual data provided by the several sensors mounted aboard and processes them.
