Floating docks and protective barriers cost often less to build than traditional fixed structures. They do not rely on heavy construction works, which can be costly and time consuming. Installing a prefabricated floating structure is generally much less disruptive to the berth’s immediate surroundings.
Together with the Rotterdam Port Authority, the Royal Boatmen Association Eendracht (KRVE) has developed the ShoreTension System. ShoreTension is a mooring system used for mooring of sea-going vessels. The basis for the development was dramatic environmental and economic losses in a number of ports caused by drifting ULCVs. Therefore, the Rotterdam Port Authority required proper action and innovations.
For this article, Walter Vervloesem decides to look at mooring issues from the port’s point of view. When mooring incidents happen in a port, port operations may be seriously disrupted. Accidents like fatalities, injuries, breakway incidents, damage to quay/wharf, other ships, cranes, pollution and so on will result in time consuming investigations, inquiries (P&I, H&M, PSC, Flagstate, Class, industry vettings, and so on) and will cause delays that might affect access to the port, stevedores’ activities and berthing schedules.
Low pressure (LP) pneumatic fenders have been in use in the offshore and port services industries for over 40 years, and have been utilized extensively for both large and small scale port operations and ship-to-ship transfers, including successful use in the Exxon Valdez oils-spill clean-up.
On 22nd February 2011, both the Queen Mary 2 and the Queen Elizabeth were due to sail into Sydney Harbor. With two of the world’s most famous cruise liners in the same place, the sponsors of the visit seized the media opportunity and thrust the event into the limelight, putting a considerable amount of extra pressure on the pilots who would take part in the operation. The ships were to come in with a five minute separation.
In recent years fendering requirements for ship-to-ship (STS) transfer operations have tended to become the preserve of high-pressure (HP) floating pneumatic fenders.The situation is supported by the current guidelines governing petroleum and LNG STS operations, which were developed on the basis of HP units that prevailed at the time of writing, but this regime may unnecessarily restrict the use of other fender types, even where these may be more appropriate for the task.
With the increase in vessel size, the question is whether the risks associated with LNG carriers maneuvering in confined water also increase. To gain greater insight into those risks, recent studies executed for several new and existing LNG terminals throughout the world include a combination of quantitative risk assessment and real-time simulations. In general, these studies are executed for the largest LNG carriers sailing worldwide.
MoorMaster™ is a vacuum-based automated mooring technology that eliminates the need for conventional mooring lines. Remote controlled vacuum pads recessed in or mounted on the quayside can moor and release vessels in seconds.
In 1989, Marimatech began the manufacturing of laser docking systems and since then has grown to become the largest supplier of such systems worldwide. When projects required the inclusion of quick release hooks (QRH), Marimatech cooperated with international manufacturers to provide a complete solution.
