New Space Saving Concept Developed for Methanol-Fueled Vessels
Lloyd’s Register (LR), in collaboration with SDC Ship Design and Consult, has developed a new concept for the use of ballast water tanks in place of cofferdams around methanol tanks, allowing ship operators more space for methanol fuel technology.For retrofits of methanol technology on existing ships, the development is expected to enable shipowners to convert their vessels without a loss of valuable space, by removing the requirement for cofferdams around fuel tanks as required by MSC.1/Circ.1621.
Concordia Damen Converts Inland Shipping Vessel into TSHD
Concordia Damen recently delivered a special project that involved the conversion of a Dutch barge into a Nigerian dredger. The trailing suction hopper dredger (TSHD) Sayonara has now arrived and is at work on the Lagos Lagoon.Three years ago, the Werkendam shipyard came into contact with a Nigerian dredging company via Damen Shipyards Gorinchem. This eventually led to the start of the complex conversion project in December 2021. After extensive testing to ensure that the vessel…
Silja Europe Propulsion Control Makeover Aims to Save 6% on Fuel
Qtagg recently secured an order on a total upgrade of Silja Europa’s propulsion control system, a makeover designed to decrease the ship’s fuel consumption by 6% and CO2 emissions by 2096 tons yearly, according to the manufacturer. The overhaul includes engine speed governors, fuel rack actuators, pitch control and voyage optimization with EcoPilot.At 59,912 gt, Silja Europa is Tallink’s largest cruise vessel. Until the summer of 2022 it operated on the Baltic Sea, between Helsinki (Finland) – Tallinn (Estonia).
Interview: Tim M. Clerc, VP Engineering, Seacor Marine
Tim Clerc’s maritime career spans half a century, starting with his cadet training in 1969 in the U.K. He sees hybrid technology as one of the most transformational technological developments in maritime in that span, and the company is currently awaiting its 10th hybrid, the Seacor Yangtze. Clerc discusses the hybrid strategy and offers some practical insights.If you had to pick one technology that you think has made the business of running ships more efficient, more cost effective…
Heger Dry Dock Gets to Work on AFDM for U.S. Navy
Born in 1998 and celebrating its 25th anniversary in 2023, Heger Dry Dock holds a unique position as one of the few engineering firms in the world dedicated to the design and lifecycle engineering of drydocks, primarily floating dry docks. Premal Shah, P.E., President and Principal Engineer, discussed some of the company’s recent contract wins with Maritime Reporter & Engineering News.Specializing in the design and lifecycle maintenance of floating dry docks, Heger Dry Docks was founded 25 years ago, and still run today by one of its co-founders, Bob Heger.
Middle East Ship Repair Yards Remain Center Stage
In the 45 years since the Arab Shipbuilding & Repair Yard (ASRY) opened on reclaimed land in Bahrain, the Middle East has become one of the world’s ship repair hotspots. A broad range of shipyards now service both regional and global markets.Regional yards have a ready market, with hundreds of offshore rigs working across the region together with the service ships that support them. Then there are thousands of tankers and gas carriers that arrive each year to load energy cargoes for far-flung destinations.
Concordia Explores Converting Tankers to Container Carriers
As the tanker market languishes and the containershipping sector drives full speed ahead, Concordia Maritime announced it has embarked on a technical design study on the feasibility of converting several of its tankers to container carriers.Concordia Maritime launched the study together with Stena Teknik and a German consulting company specializing in ship design. The aim is to investigate the feasibility of converting and adapting a P-MAX vessel for container transportation.
Shipbuilding: Is there a different future for ship repair and conversion?
There is an old adage that states that a repair yard can economically build new ships, but a new construction yard should never touch ship repair jobs. In my experience there is a lot of truth to that statement, and it does not mean that new construction yards are run by less capable people; it simply means that ship construction and ship repair and conversion are fundamentally different business models. Ship construction uses a script, while ship repair and conversion is improvisation. I will not drive the theater comparison completely home, but it has some validity.
Cummins QSK95s: Big Electric Power for Conversion of Ariake to FPSO
Floating Production Storage and Offloading (FPSO) vessels are essential tools in the search for oil in deeper waters, further from shore-based facilities. Typically, the large FPSO is stationary with a number of wells feeding oil into its holds. The oil can then be pumped off to shuttle tankers that transport it to shore side tanks and refineries.FPSOs are big expensive pieces of equipment. Some of them are converted from ocean going oil tankers. Such is the case with the 333 by 60-meter, very large crude carrier, VLCC Ariake, which was purchased for conversion to an FPSO.
Interview: Tim Leach, Glosten, Discusses Efficient Refit by Design
From 3D laser scanning to Computational Fluid Dynamics, an efficient and successful major mid-life refit such as the one completed on the RV Roger Revelle requires intricate advance design planning, an updated technical toolbelt, as well as the personal touch. Tim Leach, Principal, Naval Architect (Glosten), walks us through the process.Tim Leach, Principal, Naval Architect, Glosten.
