Submarine Power Transmission Cable Course

  • Starting from the fiscal year 2024, the tuition fees for all courses will be the same for both on-site and online attendance.
  • Payment of tuition fees is possible through credit card.
  • For those who attend the course at the on-site venue (partially including those who have taken any course in the past), an optional Goto Onsite Program will be conducted on the third day.

Please be aware of the following points regarding applications for the first half of the fiscal year 2024 at the Nagasaki Ocean Academy:
Applications for the second half of the fiscal year (October to March 2025) will be opened as soon as the schedule is determined.
Starting from the fiscal year 2024, there will be a revision of the tuition fees, so please confirm and apply accordingly.
In the second half of the fiscal year, the following courses will not be held: “A2 Offshore Wind Project Development Course,” “A3 Certification, Insurance and Finance Course,” “C2 EPC Project Management Course,” and “C3 Offshore Wind HSE Basic Course.” Please apply for these courses in the first half of the year.
The planned number of course sessions for the second half of the year at the current stage is as follows.
However, please note that this may change depending on future circumstances:
“A0 Half-Day Introductory Course” and “A1 General Course” each 2 sessions
“A4 Floating Offshore Wind Power Generation Course” and “A5 Wind and Sea Conditions Observation, Analysis, and Power Generation Forecast Course” each 1 session
“C1 Subsea Ground Survey, Analysis, and Offshore Construction Course” and “C4 Foundation Course of Power Transmission Systems” each 1 session

This course covers the essential current technologies for the submarine cable transmission system in offshore wind power projects, including cable structure design, manufacturing, quality assessment, construction, and maintenance. Participants will learn about the current state of technology and discuss future challenges and trends in this field.

The Engineering Advancement Association of Japan (ENAA) and its member companies produce the content, and experienced staff with practical knowledge serve as instructors. Japan’s offshore wind power projects have lagged behind those in Western Europe, but recently, wind farm construction has been initiated in various locations. Currently, more extensive development plans are being considered in numerous coastal areas nationwide. In the future, there is an expected significant expansion from coastal fixed-bottom wind power generation to offshore floating wind power generation. Therefore, the construction of submarine cable routes connecting wind turbines in offshore wind farms and transmitting power to onshore bases becomes crucial.

Furthermore, various related businesses exist for offshore wind power facilities. Hence, we provide essential knowledge about power transmission cables, which is highly relevant for engineers involved in these projects.”

<Important Notes>

Regarding each course,
  • Starting from November 2022, we will hold the courses in a hybrid format, combining on-site sessions at the Nagasaki Ocean Academy and online streaming.
  • When applying, please choose either “On-site” or “Online.” On-site participants will be limited to a maximum of 12 people (in order of application).
  • For those attending on-site, on the third day, we will conduct an on-site program (optional) such as visiting offshore wind turbines and installation ships, and a meeting with fishermen coexisting with offshore wind turbines in Goto.
  • However, depending on the future situation, there may be a change to holding the course exclusively online, so please be aware of this in advance.
  • The application deadline is 4 business days before the first day of the course.
  • While we strive to follow the schedule, please understand that the progress may be slightly delayed depending on the number of questions from participants.
  • If you are unable to make a reservation for any reason, please contact our academy for assistance.
Regarding the On-site Program:
  • The On-site Program incurs an additional fee separate from the course registration fee. It will be conducted on the third day for participants who have completed any of the A1 to A5 or C1 to C4 courses (including those who have taken any of these courses in the past).
  • The following are included in the participation fee: [Round-trip Jetfoil fare (Nagasaki Port to Fukue Port) *Arrangements will be made by the secretariat, and round-trip tickets will be provided before departure.] [Sea taxi usage fee] [Chartered bus usage fee] [Meeting room usage fee] [Lunch expenses (prepared in advance by the secretariat)] [Island insurance fee] (*Expenses not listed here are the participant’s responsibility).
  • Departure from Nagasaki Port at 07:40, completing site visits in Goto, and exchanging opinions with fisheries-related individuals, arriving at Nagasaki Port at 17:30 (Participants are free to go their separate ways in Goto).
  • To have both hands free on the ship, please participate with a backpack, body bag, waist pouch, etc. Additionally, due to changing weather conditions depending on the season, please participate in clothing that allows temperature regulation and comfortable movement, along with non-slip sneakers.
  • Coin lockers at Goto Fukue Port are only small, approximately 40 x 35 cm. Since the sea taxi’s interior is small, please use hotel storage or coin lockers at Nagasaki Port Terminal, etc., for large luggage. However, if you plan to bring large luggage to Goto for the return trip, please contact the secretariat in advance to secure storage, considering the return trip’s convenience and the possibility of the return Jetfoil being canceled.
  • If you are concerned about seasickness, please bring motion sickness medication.
  • Please be cautious about valuable items falling into the water. The secretariat will provide waterproof smartphone cases; please use them if necessary.
  • For those returning from Goto City without using the Jetfoil on the same day, either staying overnight or returning by air, cancel by phone before departure and proceed with ticket refund procedures at Fukue Port (a refund fee of 200 yen is required).
  • Even for those planning to stay overnight or use an airplane for the return trip, the secretariat will prepare round-trip Jetfoil tickets. Please note that we will not invoice the participation fee after deducting the return refund fee, so please understand.
  • In the case of Jetfoil, although the outbound route may be in operation, the return trip may be canceled due to sudden changes in wave conditions caused by worsening weather, etc. The final decision on cancellation is made one hour before departure. If the secretariat is informed of the cancellation decision, we will promptly notify you and coordinate the return. The return to Nagasaki will be by ferry (arriving at Nagasaki Port at 20:00, with the secretariat handling the change process) or by plane (arriving at Nagasaki Airport at 17:40, Fukuoka Airport at 18:55 – please confirm in advance). However, there is a possibility of cancellation due to weather conditions such as poor visibility. In the case of the ferry, it will not make it in time for flights to Haneda, etc., from Nagasaki Airport. On the other hand, in the case of the plane, it seems possible to transfer to flights to Haneda, etc., from both Nagasaki Airport and Fukuoka Airport, but please be careful with luggage storage.
