In my opinion, we do not generally need to keep the steering motor on while alongside. But while alongside at a berth/port with current (such as in river ports), it is strongly advised to keep at least one steering motor on.
This would prevent the rudder to move away from its mid-ship position due t
The required trim of the ship is decided during the meeting of the chief officer with docking master before the ship proceeds to the dry dock. Docking master gives the required information on the desired trim to the chief officer. Chief officer calculates the closest what he can achieve considering
A ship is detained because of a considerable port state control deficiency or multiple deficiencies.

Yes, these two surveys are usually conducted at the same time along with many other statutory surveys. But that is not a requirement to have these two surveys conducted together. These can be conducted on different dates.

The issue was raised by Marshall Island which proposed that the cooking oil should be allowed to be transferred to sludge tank and disposed of as per MARPOL Annex 1 requirements.

As per MARPOL, the word en route means
that the ship is underway at sea on a course or courses, including deviation from the shortest direct route, which as far as practicable for navigation purposes, will cause any discharge to be spread over as great an area of the sea as is reasonable and practi
The only area where incinerator cannot operate is ports, harbours, and estuaries. An estuary is the wide part of the river that nears the sea.
The incinerator can be operated in SECA also but only outside the port limits.
There is no regulation that prohibits the ship to burn residues generated
We have to admit that quantifying the garbage produced on board is a work of estimation. It is really not uncommon to find the disparity in daily production of garbage under different individuals.
This is obviously because different people may draw a different estimation of the same quantity o
Each classification society has developed its rules for the design and construction of the ships and its machinery.
These rules incorporate the standard rules developed by IACS and various IMO conventions.
Rules related to the design and construction are taken care during the construction stage. F
Let us understand this by considering a hypothetical situation. Let us assume that India has not ratified MARPOL convention. There will be further two situations in this assumption.
- India would have its own pollution prevention rules
- India does not have any pollution prevention rules

Ballast water is the talk of the town these days. Come 08th September 2017, the ballast water convention will enter into force.
And with that, there will be more and more inspections focussing on how we manage ballast water.
To avoid violation issues, it is important that we are sure of what is ex
IMDG Code specifies various conditions of the carriage of dangerous goods in packaged form. Shippers need to make sure that all these conditions are followed when shipping the dangerous goods.
For example, the dangerous goods need to be segregated as per the IMDG code to avoid two incompatible go
I just wrote a detailed guide on damage stability that includes explanation of the term floodable length and permissible length.
If you have any further question on this, do not hesitate to ask.

DPA is the link between the ship and the shore. DPA is legally bound to provide all the legitimate support to the ship.

Vetting inspections are not mandatory by statute or by law. But these inspections have become a necessity for operating a commercial ship.
The cargo owners, terminals and all other parties commercially involved with the ships want to make sure that they have a seaworthy and a safe ship.
