INTRODUCTION This article provides summaries of operational limitations of a submarine, as well as basic mechanics about how a submarine operates at the surface, underwater, between the sea surface and bottom of the seabed, and how to float back to the surface. Below are the cycles showing how a submarine operates, as illustrated in Fig. 1. To prove how this…
The world’s shipbuilding companies are concentrated in three East Asian countries – China, South Korea, and Japan – that when combined control 90% of global market share. But finally, after seven years, South Korean shipyards have recaptured the lead in annual shipbuilding orders secured, according to newly released data from Clarkson Research institute. South Korea lost its No. 1 rank…
The Fjords is to add another all-electric, zero emission passenger vessel to its fleet. The Legacy of The Fjords is under construction at Brødrene Aa and will join the hybrid Vision of The Fjords and all-electric Future of The Fjords once complete.

INTRODUCTION The atmospheric characteristics inside the submarine are importantly equal to the submarine’s major ship systems such as propulsions, navigations and sensors, weapons, auxiliaries, etc. A need to ensure an efficient and reliable health and safety of the submarine’s complements and ship machineries from atmospheric pollutants is definitely a must. To achieve and maintain this goal, an atmospheric control system…
INTRODUCTION A submarine is a hunter killer for as long as she can maintain her stealth. However, when HER PRESENCE in the immediate vicinity of the sea area is detected, then she looses her invincibility and the effective use of her weapons is denied. The submarine becomes the hunted. The exact coordinates or location of the submarine in terms of…
INTRODUCTION Stealth is the main reason for acquiring a submarine. Submarine-warfare is governed by avoiding being detected underwater by controlled sound propagation and crew activities on-board. Submarine invincibility is lost and the effective use of her weapon system would be denied once her presence underwater is detected. The submarine is a sitting duck because her location, rate of motion, and…
INTRODUCTION Don Felix B. Padilla was the first Filipino to graduate as a Naval Architect and Marine Engineer from the Massachusetts Institute of Technology (MIT, USA).

He wanted to give his fellow Filipinos…
Theo de Lange, Commercial Manager, Van Oord Offshore Wind Projects, says that despite some delayed projects, Europe’s Offshore Wind cable-laying demand is expected to grow rapidly. “UK Round 3 projects, but also German and probably also Dutch projects, are moving farther away from shore, into deeper waters. That means those vessels doing the cable-laying need to be suitable for rougher…
A fully electric zero-emission passenger vessel, Future of the Fjords, has been launched in Norway. It is the result of a collaboration between several industry partners that wanted to develop an environmentally conscious, no emissions vessel. Comprising an electric propulsion system and a Power Dock floating charging station that can take on grey and black water to ensure no sewage…
The Dutch Police has ordered six patrol vessels from Damen Shipyards for its ‘Zeehavenpolitie’ and ‘Landelijke Eenheid’ units.

A new 36m long passenger ferry, Ocean Dragon 1, has began its maiden voyage, transiting from Bantam (Indonesia) to Johor Bahru (Malaysia), and vice versa. This is a friendly collaboration between the Malaysian and Indonesian governments in creating this new route to shorten the travelling time to 1 hour and 15 minutes between the two countries. Normally, passengers would have…

A large number of abandoned or no-longer usable fiberglass vessels – including fishing vessels and leisure craft – are dumped at sea each year, possibly due to a lack of land-based disposal facilities. This was a concern raised by Pacific delegations to the Parties to the treaties, which regulate the dumping of wastes at sea. However, full data on the…

INTRODUCTION Propulsion is a means of creating force leading to the movement of a vehicle in the water, air or in land. The term is derived from Latin word “pro” meaning before or forward, and “pellere” meaning to drive. A propulsion system consists of the source mechanical power, and propulsion to convert the power into propulsive force. The main engine…
