Hydrex has developed a flexible mobdock repair method that enables the underwater replacement of all types and sizes of shaft seals. This technology has been successfully used by Hydrex diver/technicians for over a decade. It allows ship owners to keep their vessel sailing, saving precious time and money.

Damaged stern tube seals will cause an increasing amount of oil leaking or water ingress as the damage worsens. By replacing the seals when the damage is first discovered, Hydrex keeps the down time low. The ship can keep its schedule as seal repairs can be performed during cargo operations. This is done by creating a dry underwater working environment around the shaft.

It is not always straightforward to replace seals, because there can be quite a bit of variation in the configurations of the stern tube itself. There can also be complications with the liners, which can be worn down and show ruts. All this is routinely handled by Hydrex teams on the jobs.

In a recent informal poll of shipowners and operators conducted by ABS, 53 percent said their fleets were not yet ready to meet upcoming sulfur cap requirements.

ABS has issued the ABS Advisory on Marine Fuel Oil to help industry prepare for IMO’s 2020 global sulfur cap. The Advisory provides owners and operators with industry-leading guidance on the considerations and challenges with marine fuels which are likely to be used in addressing the 2020 global sulfur cap requirements.

“The IMO 2020 sulfur cap requirement will introduce a significant demand change from heavy fuel to low sulfur fuel almost overnight. The industry currently is debating how to prepare as the consequences of this shift are difficult to predict,“ said Dr. Kirsi Tikka, ABS Executive Vice President and Senior Maritime Advisor. “The ABS Advisory addresses concerns about the safety impacts and quality of the Continue reading “ABS delivers fuel advisory ahead of impending 2020 global sulfur cap offering practical guidance”

Hazards associated with dangerous goods stowage on containerships were identified on a range of boxship designs, a study conducted by Maersk Line and ABS has revealed.

The Danish shipping major giant selected ABS to lead a comprehensive Hazard Identification (HAZID) study in the aftermath of the Maersk Honam fire on March 6, 2018.

The workshop, which was launched in an effort to identify and evaluate potential hazards from dangerous cargoes stowage, identified hazards on a range of containership designs, many which are not fully addressed by the International Maritime Dangerous Goods (IMDG) Code.

A culture of poor maintenance practices led to Caribbean Fantasy fire says report

The fire could not be contained, so the master ordered the ship to be abandoned.
The fire could not be contained, so the master ordered the ship to be abandoned.

A poor safety culture and the ineffective implementation of a safety management system were identified as the most likely causes of the 2016 fire aboard the RoRo vessel Caribbean Fantasy.

The vessel’s main engine room was hit by fire in the morning hours of 17 August 2016, when fuel spraying from a leaking flange came in contact with a hot surface on the port main propulsion engine, the National Transportation Safety Board (NTSB) said in a report.

The fire could not be contained, so the master ordered the ship to be abandoned. At the time of the incident, the Baja Ferries-operated vessel was 2 miles northwest of San Juan, Puerto Rico.

German authority report suggests containers on two ships caught fire probably from self-heating

The German Federal Bureau of Maritime Casualty Investigation has released its reports about two non-connected fires on container ships. The MSC Katrina was in the Elbe estuary when the fire was detected on 20 November 2015. The second ship, the Ludwigshafen Express was in the Red Sea when fire was noticed during an inspection in February 2016.

The first incident
The MSC Katrina was located in the Elbe estuary when its smoke detection system discovered fire. As a result, the Central Command for Maritime Emergencies had the ability to deploy specially trained firefighters.
