Tulisan ini timbul setelah saya mendapat kesulitan untuk mencari jarak port to port dimana saya mendapat job mengantar atau delivery sebuah kapal.

Persoalan yg saya ingin mencari solusinya adalah saat saya mendapatkan tawaran tsbt tentu saya masih di darat dan bagaimana cara nya agar saya bisa mengetahui kira2 estimate time under way, ETA atau estimate kapan kapal berangkat dari pelabuhan dan kapan akan tiba tujuan??.. Wah belum join kapal uda pusing2 ngitung jarak di darat. Tentu ini bukan tanpa alasan, mengapa saya mencari solusi untuk hal ini ??. Alasan nya adalah karena saya sudah lebih dulu menunggu join kapal di sebuah perusahaan, Tapi karena masih stand by maka tak ada salahnya saya mengantar kpl lain untuk waktu beberapa hari, lumayan bisa buat tambahan uang saku.Jadi abis ngantar kapal kembali untuk memenuhi panggilan company lama hehe2.. Ok.

Pada tulisan saya terdahulu saya memberikan tips koreksi peta, tide predictions online Sakarang mencari jarak dgn cepat gaya mobile. Jadi cara ini bisa untuk panduang membuat garis haluan agar jarak tidak terlampau jauh dari distance table. Terutama untuk pelayaran ocean going, great circle dan juga membantu bagi anda yang tidak mau repot membuka Admiralty Distance Table.

Semua kepraktisan tentu butuh pengorbanan juga. yah butuh online. Barangkali ada software distance table yang bisa anda install di pc anda dan bekerja offline, tetapi tips ku ini bekerja secara online anda hanya perlu koneksi ke internet dimana pun anda berada lalu kunjingilah link ini.( haya untuk yang membutuhkan nya bisa comment dan aku berikan link nya). setelah terbuka anda di minta untuk memasukan beberapa data seperti :

- Leaving from (masukan pelabuhan keberangkatan)

- Going to (masukan pelabuhan tujuan)

- Time begin (masukan jam keberangkatan. Disini tidak ada pilihan untuk date karena di anggap tanggal nya adalah tanggal saat anda melakukan perhitungan)

- Speed (masukan speed rata-rata kapal anda)

Mates were in high demand during World War II.

The International Regulations for Preventing Collisions at Sea are a cornerstone of safe watchkeeping. Safety requires that one live these rules and follow the principles of safe watchkeeping. Maximizing bridge teamwork, including Bridge Resource Management is an emerging focus in watchkeeping.

The main purpose for Radar and Automatic Radar Plotting Aids (ARPA) on a ship’s bridge are to move safely among other vessels. These tools help to accurately judge information about prominent objects in the vicinity, such as:

• range, bearing, course and speed

• time and distance of closest point of approach

• course and speed changes

These factors help the officer apply the COLREGS to safely maneuver in the vicinity of obstructions and other ships.

Unfortunately, radar has a number of limitations, and ARPA inherits those limitations and adds a number of its own. Factors such as rain, high seas, and dense clouds can prevent radar from detecting other vessels. Conditions such as dense traffic and course and speed changes can confuse ARPA units. Finally, human errors such as inaccurate speed inputs and confusion between true and relative vectors add to the limitations of the radar/ARPA suite.

The radar operator must be able to optimize system settings and detect divergences between an ARPA system and reality. Information obtained from radar and ARPA has to be treated with scrutiny: over reliance on these systems has sunk ships. The officer must understand system performance. Examples include limitations and accuracy, tracking capabilities and limitations, and processing delays, and the use of operational warnings and system tests.

While a ship is underway, the officers navigate it, typically in three shifts or watches.

Celestial, terrestrial, electronic, and coastal navigation techniques are used to fix a ship’s position on a navigational chart. Accounting for effects of winds, tides, currents and estimated speed, the officer directs the helmsman to keep to track. The officer uses supplemental information from nautical publications, such as Sailing Directions, tide tables, Notices to Mariners, and radio navigational warnings to keep the ship clear of danger in transit.

Safety demands the mate be able to quickly solve steering control problems and to calibrate the system for optimum performance. Since magnetic and gyrocompasses show the course to steer, the officer must be able to determine and correct for compass errors.

Weather’s profound effect on ships requires the officer be able to interpret and apply meteorological information from all available sources. This requires expertise in weather systems, reporting procedures, and recording systems.

At sea, the mate on watch has three fundamental duties: to navigate the ship, to safely avoid traffic, and to respond to emergencies. Mates generally stand watch with able seamen who act as helmsman and lookout. The helmsman executes turns and the lookout reports dangers such as approaching ships. These roles are often combined to a single helmsman/lookout and, under some circumstances, can be eliminated completely. The ability to smartly handle a ship is key to safe watchstanding. A ship’s draught, trim, speed and under-keel clearance all affect its turning radius and stopping distance. Other factors include the effects of wind and current, squat, shallow water, and similar effects. Shiphandling is key when the need arises to rescue a man overboard, to anchor, or to moor the ship.

The officer must also be able to transmit and receive signals by Morse light and to use the International Code of Signals

A second mate is almost always a watchstander. In port and at sea, the second mate is responsible to the captain for keeping the ship, its crew, and its cargo safe for eight hours each day. Traditionally, the second mate stands a "12-4" watch: from midnight until 4am and noon until 4pm. On watch, he must enforce all applicable regulations, such as safety of life at sea and pollution regulations. In port, the watch focuses on duties such as cargo operations, fire and security watches, monitoring communications, and the anchor or mooring lines.

IMO regulations require the officer be fluent in English. This is required for a number of reasons, such as to use charts and nautical publications, understand weather and safety messages, communicate with other ships and coast stations, and to be able to work with a multi-lingual crew

A second mate (2/M) or second officer is a licensed member of the deck department of a merchant ship. The second mate is the third in command and a watchkeeping officer, customarily the ship’s navigator. Other duties vary, but the second mate is often the medical officer and in charge of maintaining distress signaling equipment. On oil tankers, the second mate usually assists the chief mate with the tank-cleaning operations.

The navigator role focuses on creating the ship’s passage plans. A passage plan is a comprehensive, step by step description of how the voyage is to proceed from berth to berth. The plan includes undocking, departure, the en route portion of a voyage, approach, and mooring at the destination.

The GMDSS officer role consists of performing tests and maintenance, and ensuring the proper log-keeping on the ship’s Global Maritime Distress Safety System equipment. Safety equipment includes Emergency Position-Indicating Radio Beacons, a NAVTEX unit, INMARSAT consoles, various radios, Search and Rescue Transponders, and Digital Selective Calling systems.

‘International Safety Management (ISM) Code means the International Management Code for the safe Operation of Ships and for Pollution Prevention

The purpose of ISM Code is:

* To ensure Safety at Sea

* To prevent human injury or loss of life

* To avoid damage to the environment and to the ship.

SOLAS adopted the ISM Code in 1994 and incorporated it into chapter IX. By 1998 much of the commercial shipping community was required to be in compliance with the ISM code. By 2002 almost all of the international shipping community was required to comply with the ISM Code.
